Windows 10 Fall 2018 Update:Updating to the newest Windows 10 Fall update? Wacom has identified a few issues within the latest update. Pan/Scroll is not working correctly in some applications. Also, Modifier Clicks do not work when assigned to pen buttons or ExpressKeys, see the screenshot below. The Wacom driver team has submitted a bug report with Microsoft for these issues and will continue to work with them until it is fixed. More information can be found here: here

Mac OS 10.14 Mojave:Upgrading to Mac OS 10.14 Mojave? A new Mac OSX security feature requires some additional changes to run the Wacom Driver correctly. Please see the instructions found on our support page here. Also, If you have any issues, please try a clean driver install. Follow the steps here.

Anyone else confirm the following issue? Or ideally, offer a solution.

On Mac OS (Currently with Mojave but also exhibited behavior on High Sierra) the front most application window looses focus at random. For instance when working in any program wether it be with image editing or even just an internet browser the front most active window will simply recede to the background as if you click/tapped on another window or the desktop etc...

While not that big of a deal when browsing it really effects the workflow when digitally painting. Several times throughout the day when attempting to paint mid brush stroke the document I'm working on looses focus. I have to click back on the document and then carry on with what I was painting. Its incredibly distracting and slows down workflow quite a bit.

This happens when using the Wacom pen or even just a mouse. Only after a Wacom Driver is installed. Uninstall the driver and the issue goes away. The issue occurs on two separate Machines. One is connected to the 27" Cintiq Touch, the other an Intuos 4.

Sounds like some app is starting and stealing focus when you are working with the Wacom tablet. There has been several instances where similar issues were reported by other Mac users but not always related to Wacom.

Since you have the same issue in 2 computers, I suspect it can be something you have installed on both. Maybe an Antivirus or a similar software that should generally only run in the background.

There are several threads you can find on google as well.

Yes, Ive already researched and found several threads online through google as you suggest. I've even read through the first 2 links that you've shared (3rd comes up as page not found) prior to posting here. Unfortunately they're a bit beyond my technical capability as it refers to saving code, running scripts, Python, and quite a bit of terminal work. Honestly I just don't know how to go about doing what the threads from the links suggest. In addition, those along the others I've come across are close to 5 years old (6 major OS updates since) as well so I'm unsure if the info is even still relevent.

I also agree that since I am experiencing the issue on both computers that it is something installed on both. The Wacom Driver is installed on both hence my concern with the tablet software. The iMac I have my Cintiq currently connected to is a brand new machine one week old with a fresh install of 10.14 Mojave so here is a complete list of what is installed beyond the standard OS install...

Someone suggested there's been a history of Wacom drivers causing the issue which is what got me started investigating my tablet software.

try creating a new user, installing the Wacom driver and install all the other software you normally have and testing it one by one.

As for creating a new user that would only eliminate the preferences as being the issue as All of the above software would still be installed for all users on the machine. Since I experienced the issue on my previous machine and am currently experiencing the issue on two separate iMacs (1 of which is new with a fresh OS install) I suspect the preferences aren't the issue.

Anyone with further insight? Experience with the issue or possibly the above apps?

Thank you for checking and for letting me know which programs you have installed. I have checked 3 Mac computers (one iMac and 2 MacBooks) with the Wacom driver installed and I have not been able to replicate this yet. If this is an issue that only happens when our driver is installed, then something else has to be causing interference with some other software.

I see that you have ran the tool from https://etrecheck.com in June. Would you mind running it again and checking for the diagnose? Check for app that may potentially run in the back ground.

I would also try checking if the issue persists in Safe mode. If you are not able the follow the more advanced steps I would recommend you I still try creating a new user and testing there.
